To all whom t may concern:

Be it known that I, PETER E. MALMsTRoM, a citizen of the United States,and a resident of the city, county, and State of New York, have inventeda new and useful Improvenient in Siphon-Bottles, of which the followingis a specification.

The object of my inventionis to provide a siphon bottle with a metalexterior, or casing, and a glass interior, or lining, suitably supportedin said casing and separated therefrom suiiiciently to leave an airchamber and also to provide suitable vents between the interior and theexterior of said lining, which will permit gas to flow, but not liquid.These and other objects are ac` complislied by my invention, oneembodiment of which is hereinafter set forth.

For a more particular description of my invention, reference is to behad to the accompanying drawings, forming a part hereof, in which,

Figure 1 is a side elevation of my improvement. Fig. 2 is a sectionalview taken on the line 2 2 of Fig. 1, looking in the direction of thearrows. Fig. 3 is a plan View of a washer. Fig. 4 is an enlargedsectional view taken on the line 4 4 of Fig. 3, looking in the directionof the arrows.

Throughout the various views of the drawings, similar referencecharacters designate similar parts.

My improved bottle 1 consists of an exterior casing 2, a glass orsimilar lining 3, a spring 4 placed on the bottom of said casing and onwhich said lining rests, a siphon head 5 supporting a siphon tube 6 inthe conventional manner, and other parts, as will appear below.

The casing 2 may be of any suitable outline, but is preferably made, asshown, with a cylindrical body 7, closed at its lower end and surroundedby a cap 8 at its upper end. The cap 8 and bottom 7 are secured togetherby solder or other suitable material. The upper end of the cap 8 forms aneck 9, which is provided with screw threads and to this is secured asiphon head of the conventional form and in the manner sh'own. The tube6 is provided with a flange 10 at its upper end, which rests on apacking 11 and forces the same in contact with the top of the neck 9.

On the interior of the cap 8 and at the base of the neck 9 is a coiledspring 12, which presses against a seat 13, of the usual form, and thisseat 13 rests on a disk 14 of rubber, or similar material, which isplaced on a flanged disk 15, the flanges running both ways, the upperflange surrounding the disk 14, and the lower flange surrounding the topof the lining 3, as shown in Fig. 2. The disk 14 is provided with twoslots 16 and 17 respectively, each of which is provided with an enlargedopening. The opening 18 is on the upper side of the disk and forms apart of the slot 16, and the opening 19 is on the lower surface of thedisk and forms a portion of the slot 17. If desired, the disk may bereversed as it can be used with either side up. It is provided with acentral perforation 20 for the tube 6.

My improved siphon is used in the usual manner and charged in theconventional way. Any excess gases can escape into the space, betweenthe lining and casing 2 through the opening 17 and there remain. Whenthe liquid is removed from the bottle, the gases between the lining andcasing return through the opening 16. Both openings 16 and 17 arenormally closed because their walls are pressed together by theelasticity of the washer, but either will open at its large end 18 or 19when a gas under pressure appears therein. Neither will open for anyliquid that is not under pressure and so these openings are liquid tightfor all practical purposes.

l/Vhile I have shown and described one embodiment of my invention, it isobvious that it is not resctricted thereto, but is broad enough to coverall structures that come within the scope of the annexed claims.

What I claim is:

1. In a device of the class described, a fluid tight outer casing havinga siphon head, a manually controlled. valve normally closing the siphonhead, a gaseous fluid container within said casing of less capacity thanthe latter to provide a space between the same, said container having aninlet vent, means closing one end of the container and having normallyclosed vents to permit escape of gas from the latter into said space,and a tube leading from the siphon head through said means into thecontainer.

2. In a device of the classdescribed, a casing, a gaseous Huid receiverof less capacity than the casing disposed therein to provide a spacetherebetween, said container having an inlet vent, siphon mechanismcarried by the casing and communicating with the re ceiver, and means onthe receiver to permit the escape of gas from the same into the saidspace.

3. In a device oit' the class described, a casing, a gaseous Huidreceiver of less capacity than the casing disposed therein to provide aspace therebetween, said container having an inlet vent, siphonmechanism carried by the casing and communicating with the receiver,means on the receiver to permit the escape of gas from the same into thesaid space, and a spring holding the said means in position on thereceiver.

l-. In a device of the class described, a casing, a receiver Within thesame of less capacity than the latter, an elastic disk mounted upon thereceiver and having normally closed inlet and outlet vents, whereby gasfree of liquid may escape from the receiver into the casing and meansholding the disk in position upon the receiver.

'In a device of the class described, an outer casing, an inner casingarranged within the latter to provide a space therebetween, said innereasing having an inlet vent, spring means between opposite ends of saidinner and outer casings, and means on the inner casing for permitting`gas free of liquid to escape from the latter into said space.

G. In a device of the class described, inner and outer casings, theinner casing being of less size than the outer casing, there being aninlet vent for the inner casing and an outlet vent, and means holdingthe inner casing firmly Within the outer casing.

7. ln a device of the class described, outer and inner casings, theinner casing being of less size than the outer casing, there being aninlet vent for the inner casing, means holding the inner casing firmlyWithin the outer casing, and means permitting excess gas pressure todischarge from the inner casing into the outer casing.

8. in a device of the class described, outer and inner casings, theinner casing being of less size than the outer casing, there being anormally .closed inlet vent for said inner casing, means holding theinner casing firmly Within the outer casing, means permitting excess gaspressure to discharge from the inner casing into the outer casing, andsiphon mechanism communicating with the inner casing.

Signed at the city of New York. countv of New York and State of NewYork, this 27th day of January, 1910.
